Headphone output loudness

The volume level of my SL400's headphone jack is insanely high. With my 80 ohm Beyerdynamic DT250 headphones, only the bottom 20% of the master volume control is usable (based on using a little app called Volume Tracker to have the "wave" volume slider move in sync with the master one). With cheaper, everyday headphones that have lower impedance, the problem is even worse.

This means I have to use an inline volume control to attenuate the output in order to increase the useful range of the volume control, and limit the maximum possible output to prevent my ears getting blasted should some piece of software spontaneously up one of the volume sliders. It's annoying having to carry around this "dongle" as a workaround.

Anyone else experienced this problem? Seems to be both a usability and safety issue.

Re: Headphone output loudness

Hello,

 

it seems that your head-phones are pretty good.

 

But the impedance is breaking at high volume levels

"the lower impedance version (80 ohm) will break down at high volumes" one user reports there.

I haven´t  heard about an impedance problem on Thinkpads, yet.

Lowering the impedance of your head-phones, by an adapter, will have an effect of lowering clarity, I think.

 

 

regards

Andreas

Re: Headphone output loudness

I only gave details about my headphones to indicate I was using a pair that are less loud at a given volume setting than what 9 out of 10 people have. Plug in lower impedance headphones, and everything I said still applies, but worse. With my 16 ohm Sennheiser CX300's for example, you can hear background hiss from the SL400's jack, and you only need to push the master/wave volume sliders to around 12% before they get dangerously loud.

I'm not sure how much using an inline volume control affects sound quality, but to me the main problem is having to cart one around just to use the laptop's headphone jack safely.

Re: Headphone output loudness

Hello,

 

please try to unistall your third-party software, it may be, that it interferred with audio drivers and

higher the sound not adquately.

After that and nothing changes I would suggest to call support and tell them your story and about your safety issue.

May be you have to send it to depot for exploration. 

But may be there´s another suggestion, from other SL user?

 

Regards

Andreas

Re: Headphone output loudness

I use iPhone's headphones, and I'm not aware about any of it's insight technical details (like the ohm level you had mentioned), and the output sound I get with it isn't too loud to blast my ears at full level while listening to music in my itunes library in Vista. YMMV.

Re: Headphone output loudness

I'm using SkullCandy Full Metal Jackets which are 16 ohm ear bud head phones.  They sound great on my sl400.  I set the master volume to about 95%, and the PCM / WAVE output to 60 to 70% and the slider on my headphones maxed, and they sound fantastic.  Little or no hiss.  It sounds like you've got some kind of software shiv in your OS that's cranking up the volume digitally and causing distortion.  I can get the same effect if I use the -af volume= setting of mplayer and go over 8 or so.  (I run ubuntu btw.)

Re: Headphone output loudness

Trikka, I have a similar issue, but haven't gotten any response on it:

 

Very high levels coming from the audio jack (headphone out), hissing during almost all sound output, and crackling / popping during any significant output.  Putting the sliders above even 8 on the software control is WAY too loud.

 

For reference, I replicated the problem using Sennheiser HD-496 and EH-350 headphones, both of which are low impedance, high quality, excellent sets of phones.  They do NOT encounter this problem while using my iPod or other audio devices.

 

Still very confused as to why this is happening...

SL 500, WinXP Pro, 2.1 GHz dual core, 2 Gb Ram

Re: Headphone output loudness

Hi there,

I purchased my Lenovo SL500 about month ago, and I'd be quite happy to figure out how to return this crap. First of all, mine came with Vista Bussines preinstaled. I hate Vista, as it's way too slow in comparison with XP and I decided do downgrade it to Windows XP using CD's provided by Lenovo. After that laptop became a lot more faster but... I tend to use headphones when working on a laptop. And the very first impression which I got was that sound from audio jack is a HELL WAY TOO LOUD. Also, every couple seconds system kept freezing for a second - it was noticable when moving cursor around. I resolved that problem by uninstalling Synaptics touchpad driver driver - in result I can't use touchpad scrolling, but at  least system is not freezing at all. Couldn't resolve problem with audio output thou, so I decided to reinstall system again but this time using original Microsoft Windows CD instead of lenovo's cd. Unfortunatelly no bloody change. Audio is still too loud, and I can't use headphones at all, as it makes my ear bleed. To be more specific - I tried Sony earphones (top of the range) and Koss headphones. Same crap on both of them.

As I remember I didn't have that problem on Vista, but instead when listening to the music sound was crackling... and that was actually one of the reasons which made me to downgrade to XP. So it looks like a driver issue. Now I'm thinking of going back to Vista. Ridiculous. Well I forgot to mention about fan noise as well, which is always on, and that's just the another highly annoying thing. I just can't get over the fact that I've chosen Lenovo SL500 over Sony's Vaio laptop which friend of mine has and is very happy with....

On my SL 500 I'm using  these.

 

They sound pretty dang sweet, especially since I've reduced the latency.  No pops or clicks, plenty of volume, just ....sweet!

 

I have a pair of Sennheiser CX400's in delivery. Curious to see how they perform.
